MANILA, Philippines - An official says a magnitude 6.5 earthquake has jolted at least five cities in the southern Philippines but says it was too deep to cause any damage or tsunami.
Philippine officials said Sunday that there were no immediate report of injuries.
Renato Solidum, who heads the Philippine Institute of Volcanology and Seismology, says the quake's epicenter was 30 kilometres southwest of Cotabato city, where residents felt their houses shake for a few seconds.
He said the quake occurred about 400 kilometres under the seabed.
The Philippine archipelago lies in the Pacific Ring of Fire where quakes are common. Earthquakes in Indonesia and off Samoa in the past week have killed hundreds in the region.
